After talking with some of our most adventurous customers, we’ve given our Altitude Tee a major make over and come up with a new, improved active Tee that’s ready for anything. We’ve kept everything that made the original Altitude Tee a firm favourite, and added some extra active styling to make sure you’re always comfortable and protected from the elements.

The new higher round neck offers extra protection, plus you’ll find the new sleeker, sportier, tapered fit is designed to suit all levels of activity. When Mother Nature throws everything she’s got at you, this one can be worn as part of a layering system. And when the temperature rises, you’ve got the perfect lightweight and breathable Tee that delivers the comfort and performance you need to go the distance.

Rest assured you’ll still find the soft-touch comfort, natural breathability, temperature regulation, moisture wicking and odor-resistance you’ve come to expect from the Altitude range made with our unique Enigma MicroMerino® fabric. It’s just got a whole new fit and feel.

(This tee has been designed to hug your body with a next to skin, contact fit, so if you want less hugs and more room, try going up a size.)

The combination of merino wool and 4% elastin in the 'Enigma' fabric ensure perfect body contact, eliminates excessive bulk, and a 4-way stretch allowing your limbs to move freely as the fabric does not inhibit your range of motion.

Antimicrobial - Moisture absorption properties reduce the tendencies for a build-up of odour.

Luxuriously soft next to skin

Breathable and temperature regulating

Ultra-comfortable warmth

Maximum warmth, minimal weight

Quick drying

All ioMerino fabrics are fully machine-washable.

Super light and breathable

Review by Alison on 3/22/17

I love this top! I've worn it on super hot days and it breathes so well, doesn't leave you smelly or soaked in sweat. Will still keep you warm under a jumper too.
Much better than my Kathmandu shirts.

Better than Icebreaker Tech Lite

Review by JK Rivers on 2/10/17

I'm 5'7" and 140 lbs. Bought both Medium and Small when this shirt was on sale and I prefer the small as it holds its place better. Might not pay $85 for it but that's only because I'm broke. Better than the Icebreaker tech lite equivalent (which I also own) because it is less stiff (lighter). This is my favorite merino T-shirt I've found. Black all the way even though cat hair sticks to it like a mo fo. Can't speak for longevity yet but it's been 2 months and no issues yet.
